The Standard of Excellence

The highest quality for the most demanding applications.

At United Industries, we have nearly 70 years of experience meeting and exceeding the standard for welded stainless steel tubing. Our corporate philosophy ensures customer satisfaction and superior products.

Never Ending Improvement:  We embrace state-of-the-art technology, outstanding customer service, competitive pricing, and a commitment to 100% on-time delivery and zero defective parts.

State-of-the-Art Manufacturing: Repeatable, documented process control allows us to ensure consistent top quality for every product, every time, every day.

Quality Assurance: Our products exceed ASTM test requirements – your assurance of excellence. Our inline eddy current testing for all parts helps ensure a high-quality final product by identifying non-conformities during the manufacturing process.

From source material to shipping, the ultimate in quality at every step.

Raw Materials: We purchase only from select USA suppliers to meet United Industries’ tight chemical and mechanical specifications.

High Purity Welds: We assure the highest quality through Laser Welding systems.

Weld Reduction: To ensure smooth bores and improved flow characteristics, United Industries’ stainless steel tubing is manufactured using a continuous roll or reciprocating ironing.

Annealing: United Industries stainless steel tubing is induction annealed to meet ASTM requirements or customer specifications and is rapidly quenched. This process improves stress relief, resulting in improved fabrication and formability.

Inline polishing: Our inline polishing is followed by immediate end-capping and polywrapping to ensure surface purity for all sanitary and pharmaceutical stainless steel tubing.

Advanced tube polishing techniques: United Industries offers the finest surface finish in the industry, exceeding current standards.
